Neither is universally better. Area size, whether you can shave, and how much density you need decide it.
FUE opens recipient channels first, then places grafts into them. DHI loads each graft into a Choi implanter pen that opens the channel and places the follicle in one movement. Everything else — extraction, anaesthesia, aftercare — is the same.
Large areas. Because channels are opened in a controlled sequence, the surgeon can plan density across a whole region and place 4,000+ grafts efficiently in a single day. For a Norwood 4–5 covering hairline and crown, FUE is the pragmatic choice.
Precision and unshaven cases. The pen controls angle and depth per follicle, which matters most on the frontal line and for women who cannot shave. Grafts also spend less time outside the body.
Most male cases: Sapphire FUE, often with DHI used for the frontal hairline only — a hybrid that gets density where it is needed and precision where it shows. Women and unshaven requests: DHI throughout.
For hairline detail and unshaven treatment, yes. For covering a large bald crown, the money is better spent on more grafts with FUE.
